Chihuahuan Raven -- Corvus cryptoleucus
(formerly White-necked Raven)

RANGE: Resident from south-central and southeastern Arizona, central and northeastern New Mexico, northeastern Colorado, and south-central Nebraska south to Mexico, and east to western Kansas and central Texas. (Northeastern populations, especially those in Nebraska and Kansas, migrate southward in winter.)

STATUS: Locally common.

HABITAT: Favors open, arid grasslands interspersed with yucca, mesquite, and cactus. Also occurs in deserts, on the open plains, and in arid farmlands, extending into the foothills. Outside the breeding season, often forms large flocks and roosts communally in canyons and gulches.

NEST: Usually builds nest in isolated trees or bushes, 4 to 40 feet above the ground; often uses same nest year after year. Uses sycamore, mesquite, willow, oak, yucca, cottonwood and other species for nest sites, but also nests on utility poles and windmill towers.

FOOD: Typically eats insects, especially grasshoppers and beetles, cultivated grains, small reptiles, fruits of cacti, carrion, eggs and young of birds, and scraps of human food.
